Barriers to accessing care for cardiometabolic disorders in Malawi: partners as a source of resilience for people living with HIV

BackgroundPeople living with HIV (PLWH) are at increased risk of cardiometabolic disorders (CMD). Adequate access to care for both HIV and CMD is crucial to improving health outcomes; however, there is limited research that have examined couples’ experiences accessing such care in resource-constrained settings. We aimed to identify barriers to accessing CMD care among PLWH in Malawi and the role of partners in mitigating these barriers.MethodsWe conducted a qualitative investigation of barriers to CMD care among 25 couples in Malawi. Couples were eligible if at least one partner was living with HIV and had hypertension or diabetes (i.e., the index patient). Index patients were recruited from HIV care clinics in the Zomba district, and their partners were enrolled thereafter. Interviews were conducted separately with both partners to determine barriers to CMD care access and how partners were involved in care.ResultsParticipants framed their experiences with CMD care by making comparisons to HIV treatment, which was free and consistently available. The main barriers to accessing CMD care included shortage of medications, cost of tests and treatments, high cost of transportation to health facilities, lengthy wait times at health facilities, faulty or unavailable medical equipment and supplies, inadequate monitoring of patients’ health conditions, some cultural beliefs about causes of illness, use of herbal therapies as an alternative to prescribed medicine, and inadequate knowledge about CMD treatments. Partners provided support through decision-making on accessing medical care, assisting partners in navigating the healthcare system, and providing financial assistance with transportation and treatment expenses. Partners also helped manage care for CMD, including communicating health information to their partners, providing appointment reminders, supporting medication adherence, and supporting recommended lifestyle behaviors.ConclusionsCouples identified many barriers to CMD care access, which were perceived as greater challenges than HIV care. Partners provided critical forms of support in navigating these barriers. With the rise of CMD among PLWH, improving access to CMD care should be prioritized, using lessons learned from HIV and integrated care approaches. Partner involvement in CMD care may help mitigate most barriers to CMD care.

Innovations and adaptations in neonatal and pediatric respiratory care for resource constrained settings.

Respiratory disease is a leading cause of death in children under 5 years of age worldwide, and most of these deaths occur in low- to middle-income countries (LMICs) where advanced respiratory care technology is often limited. Much of the equipment required to provide advanced respiratory care is unavailable in these areas due to high costs, the need for specialty trained personnel, and myriad other resource constraints that limit uptake and sustainable use of these devices, including reliable access to electricity, sensitive equipment needing frequent maintenance, single-patient-use supplies, and lack of access to sterilization equipment. Compounding the problem, pediatrics is uniquely challenging in that one size does not fit all, or even most patients. Despite these substantial barriers, numerous innovations in respiratory care technology have been made in recent years that have brought increasing access to high quality respiratory care in some of the most remote areas of the world. In this article, we intend to review the global burden of respiratory diseases for children, highlight the prototypical innovations that have been made in bringing respiratory care to LMICs, spotlight some of the technologies being actively developed to improve respiratory care in resource-constrained settings, and conclude with a discussion highlighting areas where further innovation is still needed.

Challenge of managing hepatitis B virus and hepatitis C virus infections in resource-limited settings.

The global burden of hepatitis B virus (HBV) and hepatitis C virus (HCV) infections and coinfection represents a major public health concern, particularly in resource-limited settings. Elimination of HCV by 2030 has become foreseeable, with effective direct-acting antiviral oral therapies and the availability of affordable generics in low-and-middle-income countries (LMICs). However, access to oral nucleos(t)ide therapy for HBV remains critical and is limited outside the existing global HIV program platforms despite affordable prices. Prevention of mother-to-child transmission of HBV through scaling up of birth dose implementation in LMICs is essential to achieve the 2030 elimination goal. Most individuals living with HBV and/or HCV in resource-limited settings are unaware of their infection, and with improved access to medications, the most significant barrier remains access to affordable diagnostics and preventive strategies. The coronavirus disease 2019 pandemic interrupted hepatitis elimination programs, albeit offered opportunities for improved diagnostic capacities and raised political awareness of the critical need for strengthening health care services and universal health coverage. This review underpins the HBV and HCV management challenges in resource-limited settings, highlighting the current status and suggested future elimination strategies in some of these countries. Global efforts should continue to improve awareness and political commitment. Financial resources should be secured to access and implement comprehensive strategies for diagnosis and linkage to care in resource-constrained settings to fulfill the 2030 elimination goal.

Impact of newly constructed primary healthcare centres on antenatal care attendance, facility delivery and all-cause mortality: quasi-experimental evidence from Taabo health and demographic surveillance system, Côte d’Ivoire

ObjectivesAccess to quality care remains limited, particularly in low-income and middle-income countries. Although better health outcomes for families living in close proximity to healthcare facilities have been documented in cross-sectional...

Managing ancillary care in resource-constrained settings: Dilemmas faced by frontline HIV prevention researchers in a rural area in South Africa.

BackgroundWe describe the findings from a research ethics case study, linked with a team evaluating a package of intervention services to prevent HIV infection in adolescent girls and young women (AGYW) living in a rural and poor setting of KwaZulu-Natal, South Africa.MethodsWe conducted qualitative interviews (n=77) with members of the linked research team evaluating the intervention programme, programme implementing staff, AGYW enrolled in the intervention programme, caregivers, ethics committee members, Public Engagement officers, community advisory board members and community stakeholders. Data were analysed iteratively using thematic framework analysis. Themes were determined by the study aims combined with an inductive development of codes emerging from the data.ResultsThe findings show that the burden of providing ancillary care fell primarily on the shoulders of frontline researchers and programme staff. Dilemmas around responding to gender-based violence illustrated the limits of ‘referral to services’ as a solution for meeting ancillary care obligations in contexts with barriers to basic health and social services.ConclusionOur findings show important gaps in meeting ancillary care needs. Participants’ needs required social and economic support which frontline researchers and implementing partners were not able to meet, causing moral distress.

Households in HIV Care: Designing an Intervention to Stimulate HIV Competency in Households in South Africa.

Despite the Universal Test and Treat program and widespread antiretroviral treatment rollout, South Africa is still facing HIV prevention and treatment challenges, which are aggravated by human resource shortages in the healthcare sector. Individual- and community-level responses to these HIV-related challenges are increasingly being explored, for example, in community and home-based care. The role of the household as a crucial mediating social level has, however, largely been omitted. This paper outlines the design of an intervention to stimulate the involvement of the household in support for people living with HIV in South Africa. The 6SQuID model guided the intervention development process in four phases: (1) formative research, theory formulation, and a review of the existing literature, (2) integration of the results from the formative research into the “Positive Communication Process” (P2CP model) as a mechanism of change, (3) design of a community-health-worker-led intervention as the way to deliver the change mechanism, and (4) testing and revision of the developed intervention material—called Sinako—in a small-scale pilot study. The Sinako intervention anticipates that the future of chronic HIV care in resource-constrained settings will need to integrate the patient's household into the fight against HIV.

ASCO Guideline report: Palliative Care in the Global Setting—ASCO Resource-Stratified Practice Guideline.

85 Background: The purpose of the new ASCO resource-stratified guideline on global palliative care (Osman H, Shrestha S, Temin S, et al, Palliative Care in the Global Setting: ASCO Resource-Stratified Practice Guideline, JGO, 2018) is to provide expert guidance to clinicians and policymakers on implementing palliative care in resource-constrained settings and was intended to complement the 2016 “Integration of Palliative Care Into Standard Oncology Care: American Society of Clinical Oncology Clinical Practice Guideline Update”. Methods: ASCO convened a multidisciplinary, multinational panel of experts. Guideline development involved a systematic review, a modified ADAPTE process of existing high-quality guidelines and a formal consensus-based process with the expert panel and additional experts (consensus ratings group), as well as open comment. Results: The systematic review included 48 full-text publications regarding palliative care in resource-constrained settings, along with cost-effectiveness analyses; the evidence for many clinical questions was limited. These provided indirect evidence to inform the formal consensus process, which resulted in agreement of ≥ 75% (by consensus ratings group including expert panel). Conclusions: The recommendations help define: the models of care, staffing requirements, and roles and training needs of team members in a variety of resource settings for palliative care. Recommendations also outline the standards for provision of psychosocial support, spiritual care, and opioid analgesics, which can be particularly challenging and often overlooked in resource-constrained settings.

Accuracy of Mobile Phone and Handheld Light Microscopy for the Diagnosis of Schistosomiasis and Intestinal Protozoa Infections in Côte d'Ivoire.

BackgroundHandheld light microscopy using compact optics and mobile phones may improve the quality of health care in resource-constrained settings by enabling access to prompt and accurate diagnosis.MethodologyLaboratory technicians were trained to operate two handheld diagnostic devices (Newton Nm1 microscope and a clip-on version of the mobile phone-based CellScope). The accuracy of these devices was compared to conventional light microscopy for the diagnosis of Schistosoma haematobium, S. mansoni, and intestinal protozoa infection in a community-based survey in rural Côte d’Ivoire. One slide of 10 ml filtered urine and a single Kato-Katz thick smear from 226 individuals were subjected to the Newton Nm1 microscope and CellScope for detection of Schistosoma eggs and compared to conventional microscopy. Additionally, 121 sodium acetate-acetic acid-formalin (SAF)-fixed stool samples were examined by the Newton Nm1 microscope and compared to conventional microscopy for the diagnosis of intestinal protozoa.Principal FindingsThe prevalence of S. haematobium, S. mansoni, Giardia intestinalis, and Entamoeba histolytica/E. dispar, as determined by conventional microscopy, was 39.8%, 5.3%, 20.7%, and 4.9%, respectively. The Newton Nm1 microscope had diagnostic sensitivities for S. mansoni and S. haematobium infection of 91.7% (95% confidence interval (CI) 59.8–99.6%) and 81.1% (95% CI 71.2–88.3%), respectively, and specificities of 99.5% (95% CI 97.0–100%) and 97.1% (95% CI 92.2–99.1%), respectively. The CellScope demonstrated sensitivities for S. mansoni and S. haematobium of 50.0% (95% CI 25.4–74.6%) and 35.6% (95% CI 25.9–46.4%), respectively, and specificities of 99.5% (95% CI 97.0–100%) and 100% (95% CI 86.7–100%), respectively. For G. intestinalis and E. histolytica/E. dispar, the Newton Nm1 microscope had sensitivity of 84.0% (95% CI 63.1–94.7%) and 83.3% (95% CI 36.5–99.1%), respectively, and 100% specificity.Conclusions/SignificanceHandheld diagnostic devices can be employed in community-based surveys in resource-constrained settings after minimal training of laboratory technicians to diagnose intestinal parasites.

Engineering long shelf life multi-layer biologically active surfaces on microfluidic devices for point of care applications.

Although materials and engineered surfaces are broadly utilized in creating assays and devices with wide applications in diagnostics, preservation of these immuno-functionalized surfaces on microfluidic devices remains a significant challenge to create reliable repeatable assays that would facilitate patient care in resource-constrained settings at the point-of-care (POC), where reliable electricity and refrigeration are lacking. To address this challenge, we present an innovative approach to stabilize surfaces on-chip with multiple layers of immunochemistry. The functionality of microfluidic devices using the presented method is evaluated at room temperature for up to 6-month shelf life. We integrated the preserved microfluidic devices with a lensless complementary metal oxide semiconductor (CMOS) imaging platform to count CD4+ T cells from a drop of unprocessed whole blood targeting applications at the POC such as HIV management and monitoring. The developed immunochemistry stabilization method can potentially be applied broadly to other diagnostic immuno-assays such as viral load measurements, chemotherapy monitoring, and biomarker detection for cancer patients at the POC.

Implementation Science for Global Oncology: The Imperative to Evaluate the Safety and Efficacy of Cancer Care Delivery.

The development of cancer care treatment facilities in resource-constrained settings represents a challenge for many reasons. Implementation science-the assessment of how services are set up and delivered; contextual factors that affect delivery, treatment safety, toxicity, and efficacy; and where adaptations are needed-is essential if we are to understand the performance of a treatment program, know where the gaps in care exist, and design interventions in care delivery models to improve outcomes for patients. The field of implementation science in relation to cancer care delivery is reviewed, and the experiences of the integrated implementation science program at the Butaro Cancer Center of Excellence in Rwanda are described as a practical application. Implementation science of HIV and tuberculosis care delivery in similar challenging settings offers some relevant lessons. Integrating effective implementation science into cancer care in resource-constrained settings presents many challenges, which are discussed. However, with carefully designed programs, it is possible to perform this type of research, on regular and ongoing bases, and to use the results to develop interventions to improve quality of care and patient outcomes and provide evidence for effective replication and scale-up. Implementation science is both critical and feasible in evaluating, improving, and supporting effective expansion of cancer care in resource-limited settings. In ideal circumstances, it should be a prospective program, established early in the lifecycle of a new cancer treatment program and should be an integrated and continual process.

Task shifting in surgery: Lessons from an Indian Heart Hospital

We present a case study that illustrates task shifting, the transfer of activities from senior to junior colleagues, in the context of cardiac surgery at the Narayana Health City Cardiac Hospital (NH) in India. The case discusses the factors driving the adoption of task shifting at NH and identifies the implications of task shifting for surgeon training, surgical capacity, and procedure costs. A comparison of the outcomes of two senior surgeons with similar experience, workload, and patient profiles—but varying in their level of task shifting—suggests that shifting of lower complexity tasks by senior surgeons to trained junior colleagues does not negatively impact in-hospital mortality and post-procedure length of stay. The study concludes with a discussion of task shifting’s potential to improve access to affordable tertiary care in resource-constrained settings.

Integrating cervical cancer prevention initiatives with HIV care in resource-constrained settings: A formative study in Durban, South Africa

Cervical cancer screening rates remain suboptimal among women in South Africa (SA), where cervical cancer prevalence is high. The rollout of HIV-related services across SA may provide a means to deliver cervical cancer screening to populations with limited access to health care systems. In this mixed methods study, psychosocial factors influencing cervical cancer prevention and perceptions of the provision of Pap smears in HIV care settings were examined. Structured interviews were conducted with women (n = 67) from a municipal housing estate in Durban, SA. Key informants (n = 12) also participated in semi-structured interviews. Findings revealed that participants had low cervical cancer knowledge, but desired more information. Relevant themes included the normalisation of HIV and beliefs that cervical cancer might be worse than HIV. A comprehensive community clinic was desired by most, even if HIV-positive patients were treated there. This study provides important insight into integrating cervical cancer screening with HIV clinics, which may increase cancer screening among South African women.

Rewards and challenges of providing HIV testing and counselling services: health worker perspectives from Burkina Faso, Kenya and Uganda.

The rapid scale-up of human immunodeficiency virus (HIV) testing, counselling and treatment throughout sub-Saharan Africa has raised questions about how to protect patients' rights to consent, confidentiality, counselling and care in resource-constrained settings. The Multi-country African Testing and Counselling for HIV (MATCH) study investigated client and provider experiences with different modes of testing in sub-Saharan Africa. One component of that study was a survey of 275 HIV service providers in Burkina Faso, Kenya and Uganda that gathered quantifiable indicators and qualitative descriptions using a standardized instrument. This article presents provider perspectives on the challenges of obtaining consent, protecting confidentiality, providing counselling and helping clients manage disclosure. It also explores health workers' fear of infection within the workplace and their reports on discrimination against HIV clients within health facilities. HIV care providers in Burkina Faso, Kenya and Uganda experienced substantial rewards from their work, including satisfaction from saving lives and gaining professional skills. They also faced serious resource constraints, including staff shortages, high workloads, lack of supplies and inadequate infrastructure, and they expressed concerns about accidental exposure. Health workers described heavy emotional demands from observing clients suffer emotional, social and health consequences of being diagnosed with HIV, and also from difficult ethical dilemmas related to clients who do not disclose their HIV status to those around them, including partners. These findings suggest that providers of HIV testing and counselling need more resources and support, including better protections against HIV exposure in the workplace. The findings also suggest that health facilities could improve care by increasing attention to consent, privacy and confidentiality and that health policy makers and ethicists need to address some unresolved ethical dilemmas related to confidentiality and non-disclosure, and translate those discussions into better guidance for health workers.

Organisational innovation and control practices: the case of public–private mix in tuberculosis control in India

Partnerships between public and private healthcare providers are often seen as an important way to improve health care in resource-constrained settings. Despite the reconfirmed policy support for including private providers into public tuberculosis control in India, the public-private mix (PPM) activities continue to face apprehension at local implementation sites. This article investigates the causes for those difficulties by examining PPM initiatives as cases of organisational innovation. It examines findings from semi-structured interviews, observations and document analyses in India around three different PPM models and the attempts of innovating and scaling up. The results reveal that in PPM initiatives underlying problem definitions and different control practices, including supervision, standardisation and culture, continue to clash and ultimately hinder the scaling up of PPM. Successful PPM initiatives require organisational control practices which are rooted in different professions to be bridged. This entails difficult balancing acts between innovation and control. The innovators handle those differently, based on their own ideas of the problem that PPM should address and their own control practices. We offer new perspectives on why collaboration is so difficult and show a possible way to mitigate the established apprehensions between professions in order to make organisational innovations, such as PPM, sustainable and scalable.

Narratives of distress about birth in South African public maternity settings: A qualitative study

Objectiveto explore the factors associated with negative birth experiences in South African public maternity settings from the perspective of women's birth narratives. Designan explorative, qualitative research study using a narrative methodological framework and unstructured interviewing. Settingthe city of Cape Town in South Africa. Participants33 low-income women aged 18–42 years who had recently given birth to an infant in the public maternity sector. Findingsmore than half of the women (n=18) narrated ‘narratives of distress’ in relation to their birth experiences. One third narrated ‘good’ birth experiences and four women told minimalistic or neutral birth narratives. This paper reports only on factors associated with women's distress narratives. Narratives of distress were associated with poor quality of intrapartum care and characterised by the following four themes, namely (1) negative interpersonal relations with caregivers, (2) lack of information, (3) neglect and abandonment and (4) the absence of a labour companion. Key conclusions and implications for practicepoor relationships with caregivers emerged as central to women's distress narratives. Interventions aimed at improving interpersonal communication, connection and rapport between caregivers and labouring women are central to improving quality of care in resource-constrained settings.

Promoting Excellence in the Care of Pediatric Endocrine Diseases in the Developing World

On behalf of the Global Pediatric Endocrinology and Diabetes group, the authors provide a perspective on the rights of a child as enshrined in the United Nations Convention on the Rights of the Child (1989) concerning the care of pediatric endocrine disorders and diabetes mellitus, throughout the world, with particular reference to care in resource-constrained settings. In this article, we define the spectrum of health care needs of the child with an endocrine disorder and how they may be addressed, in terms of education, research, and development of sustainable programs for improved health outcomes. We emphasize the responsibilities of medical communities, the pharmaceutical industry, and relevant governments in promoting and supporting such concepts.

The effect of electronic medical record-based clinical decision support on HIV care in resource-constrained settings: A systematic review

BackgroundIt is estimated that one million people infected with HIV initiate anti-retroviral therapy (ART) in resource-constrained countries annually. This occurs against a background of overburdened health workers with limited skills to handle rapidly changing treatment standards and guidelines hence compromising quality of care. Electronic medical record (EMR)-based clinical decision support systems (CDSS) are considered a solution to improve quality of care. Little evidence, however, exists on the effectiveness of EMR-based CDSS on quality of HIV care and treatment in resource-constrained settings. ObjectiveThe aim of this systematic review was to identify original studies on EMR-based CDSS describing process and outcome measures as well as reported barriers to their implementation in resource-constrained settings. We characterized the studies by guideline adherence, data and process, and barriers to CDSS implementation. MethodsTwo reviewers independently assessed original articles from a search of the MEDLINE, EMBASE, CINAHL and Global Health Library databases until January 2012. The included articles were those that evaluated or described the implementation of EMR-based CDSS that were used in HIV care in low-income countries. ResultsA total of 12 studies met the inclusion criteria, 10 of which were conducted in sub-Saharan Africa and 2 in the Caribbean. None of the papers described a strong (randomized controlled) evaluation design. Guideline adherence: One study showed that ordering rates for CD4 tests were significantly higher when reminders were used. Data and process: Studies reported reduction in data errors, reduction in missed appointments, reduction in missed CD4 results and reduction in patient waiting time. Two studies showed a significant increase in time spent by clinicians on direct patient care. Barriers to CDSS implementation: Technical infrastructure problems such as unreliable electric power and erratic Internet connectivity, clinicians’ limited computer skills and failure by providers to comply with the reminders are key impediments to the implementation and effective use of CDSS. ConclusionThe limited number of evaluation studies, the basic and heterogeneous study designs, and varied outcome measures make it difficult to meaningfully conclude on the effectiveness of CDSS on quality of HIV care and treatment in resource-limited settings. High quality evaluation studies are needed. Factors specific to implementation of EMR-based CDSS in resource-limited setting should be addressed before such countries can demonstrate its full benefits. More work needs to be done to overcome the barriers to EMR and CDSS implementation in developing countries such as technical infrastructure and care providers’ computer illiteracy. However, simultaneously evaluating and describing CDSS implementation strategies that work can further guide wise investments in their wider rollout.
